Hey everybody. I am considering taking an extra 10 gallon tank I have laying around and making a little refugium under my 150 gal
. mixed reef. I plan on running the refugium separate from my sump because my sump is basically full.
What I plan on doing is putting the 10 gallon up on a small stand so that it is able to siphon water out of the refugium and back into the sump with a simple overflow. Then I can just pump water into the refugium from the sump either by the T-joint I have on the return line of the main sump pump, or by adding a small power head into the sump and pumping the water up and into the refugium.
I have never done one of these venturi siphon type overflow boxes.
What is there to know? If the water source stops pumping water into the refugium, then the siphon will break? And then, if the power comes back on it floods. Right? So how do you handle this situation?
Anything else I should know about my plan?
